IMPROVEMENT IN SLEEVE-BUTTONS.

Specification fonning part of Letters Patent No. 196,001, dated October 9, 1877; application filed February 24, 1877.

To all whom it may concern:

Be it known that I, ADoLPnUs L. FRANK ENTIIAL, of Boston, in the county of Suffolk and State of Massachusetts, have invented a ncwand useful Improvement in Slc eve-Button, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure l is a side elevation of a sleeve-button embodying my invention. Fig. 2 is a pen spective view, showing the two portions of the button separated. Fig. 3 is avertical section. Fig. 4 is a horizontal section 011 line as 00, Fig. 1. Fig. 5 is a part section enlarged.

Similar letters of reference indicate corresponding parts.

This improvement is intended to be applied not only to sleeve-buttons, but also to collarbuttons, studs, and the like.

it represents the upper or outer, and b the lower or inner, plate in a sleeve-button. Pro jecting upward from the plate is a straight tubular post or stem, 0. Projecting downward from the plate a is the straight solid stem (1.

30th the tubular post 0 and the stem d are made straight. This is an improvement over tapered or cone-shaped posts, being cheaper in manufacture, less difiicult to operate, and subject to less strain in practical use.

The stem (Z is provided with two cuts, 0 and c, the two forming a cross-cut. The object of this is to facilitate the entrance of the stem (1 into the tube 0.

The cut 0 is a shorter and the cut 6 is a longer cut, the purpose being to equalize or graduate the pressure as the stem. is forced into the tube, thus preventing the pressure and friction from being too prominent or apparent at any one point. Thus the short cut 0 is first used, and then the longer cut 0, in putting the sleevebutton together.

In use, the tubular post 0 is passed through the buttonhole from the inside, and the stem cl is then pressed into said post from the outside, and the s1eeve-butt0n is in place.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

In combination with the back plate 1), provided with the straight tubular post 0, the plate a, provided with the straight stem cl, of even thickness, said stem having the crosscut c e, of different lengths, substantially as and for the purpose herein set forth.
